The S25FL064LABNFV013: It uses the SPI - Quad I/O and QPI interface, clocking at 108 MHz for fast read and program operations. The exposed-pad package (WSON 5x6 mm) helps pull heat out during sustained write cycles — a detail worth noting if the layout has a thermal via stitch under the pad.
Lifecycle and supply — no end-of-life concern
The part is ROHS3 compliant.
Package and thermal — the exposed pad matters
Without that thermal connection, the part may throttle or exceed the rated temperature in a high-ambient enclosure.
